 # NBA_Go
 
-## First‑time bootstrap
+A high-performance NBA statistics REST API built with Go (Fiber), PostgreSQL, and NGINX. Data is scraped from Basketball Reference and served through a load-balanced, containerized stack with built-in observability.
 
-```bash
+## Architecture
-# 1. build + run
-docker-compose up --build -d
-
-# 2. create API key (ADMIN_SECRET is loaded from .env)
-curl -XPOST http://localhost:8080/admin/keys \
-  -H "X-Admin-Secret: $ADMIN_SECRET" \
-  -d '{"label":"local-test"}'
-# → { "id":1, "apiKey":"ab12cd…" }
-
-# 3. call a protected endpoint
-curl http://localhost:8080/api/playeradvancedstats \
-     -H "X-API-Key: ab12cd…"

+
+## API Endpoints
+
+| Method | Path | Description |

+| POST | `/admin/keys` | Create API key (requires `X-Admin-Secret` header) |
+
+### Query Parameters (all data endpoints)
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `page` | int | Page number (default: 1) |
+| `pageSize` | int | Results per page (default: 20) |
+| `sortBy` | string | Field to sort by (varies per endpoint) |
+| `ascending` | bool | Sort direction (default: false / descending) |
+| `season` | int | Filter by season year (e.g., 2025) |
+| `team` | string | Filter by team abbreviation (e.g., LAL, BOS) |
+| `playerId` | string | Filter by player ID (e.g., jamesle01) |
+| `isPlayoff` | bool | Filter for playoff stats |
+
+#### Games-specific parameters
+
+| Parameter | Type | Description |
+|-----------|------|-------------|
+| `date` | string | Filter by date (YYYY-MM-DD) |
+| `gameId` | string | Filter by specific game ID |
+| `include` | string | Comma-separated associations to preload: `lineScores`, `playerGameBasicStats`, `playerGameAdvStats`, `teamGameBasicStats`, `teamGameAdvStats` |
+
+### Example Requests
+
+```bash
+# Get top scorers for the 2025 season
+curl "http://localhost:8080/api/playertotals?season=2025&sortBy=points&pageSize=10"
+
+# Get a specific game with full box score
+curl "http://localhost:8080/api/games?gameId=202501010LAL&include=lineScores,playerGameBasicStats,teamGameBasicStats"
+
+# Get LeBron's advanced stats across all seasons
+curl "http://localhost:8080/api/playeradvancedstats?playerId=jamesle01&sortBy=season&ascending=true"
+
+# Get shot chart data for Curry in 2024
+curl "http://localhost:8080/api/playershotchart?playerId=curryst01&season=2024"
+```
+
+### Response Format
+
+All endpoints return paginated JSON:
+
+```json
+{
+  "data": [...],
+  "pagination": {
+    "total": 450,
+    "page": 1,
+    "pageSize": 20,
+    "pages": 23
+  }
+}
+```
+
+## Rate Limiting
+
+The API enforces a per-IP rate limit of **20 requests per minute per instance**. With 3 instances behind NGINX round-robin, the effective limit is ~60 requests/minute per client.
+
+Exceeding the limit returns:
+
+```json
+HTTP 429
+{"error": "Rate limit exceeded. Try again later."}
+```
+
+## Getting Started
+
+### Prerequisites
+
+- Docker & Docker Compose
+- Go 1.23+ (for local development)
+- A `.env` file with database credentials
+
+### Environment Variables
+
+```env
+DB_HOST=postgres
+DB_USER=your_user
+DB_PASSWORD=your_password
+DB_NAME=your_db
+DB_PORT=5432
+ADMIN_SECRET=your_admin_secret
+```
+
+### Local Development
+
+```bash
+# Start everything (Postgres, 3 API instances, NGINX, Prometheus, Grafana)
+docker-compose -f docker-compose.local.yml up --build -d
+
+# Or use the Makefile shortcut
+make up
+```
+
+Services will be available at:
+
+| Service | URL |
+|---------|-----|
+| API (via NGINX) | http://localhost:8081 |
+| Prometheus | http://localhost:9090 |
+| Grafana | http://localhost:3001 (admin/testing) |
+| API instance 1 (direct) | http://localhost:5001 |
+| API instance 2 (direct) | http://localhost:5002 |
+| API instance 3 (direct) | http://localhost:5003 |
+
+### Importing Data
+
+The application has a dual-mode entry point. To run the initial data import (migrations + scraping):
+
+```bash
+docker-compose -f docker-compose.local.yml run --rm db-init
+```
+
+This runs `main.go` with the `import-data` argument, which:
+1. Runs all GORM AutoMigrate operations
+2. Scrapes Basketball Reference for player advanced stats, totals, game schedules, and box scores
+3. Upserts all data into PostgreSQL
+
+### Stopping
+
+```bash
+docker compose down
+# or
+make down
+```
+
+## Production Deployment
+
+The main `docker-compose.yml` is configured for deployment on Coolify with an external `coolify` network. It expects the database to be provisioned separately (no local Postgres service).
+
+The `docker-compose.override.yml` disables the local Postgres container and removes `depends_on` constraints, allowing API services to connect to a remote database specified in `.env`.
+
+## Observability
+
+### Prometheus Metrics
+
+Exposed at `/metrics` on each API instance. Tracked metrics:
+
+- `nba_http_requests_total` — counter by method, endpoint, status
+- `nba_http_request_duration_seconds` — histogram by method, endpoint
+- `nba_db_operations_total` — counter by operation, entity
+
+### Grafana
+
+Pre-provisioned dashboards visualize request rates and endpoint usage. Access at port 3001 (local) or 3000 (production).
+
+## API Key Management (Optional)
+
+API key authentication is available but currently disabled. To create keys for future use:
+
+```bash
+# Create a key
+curl -XPOST http://localhost:8080/admin/keys \
+  -H "X-Admin-Secret: $ADMIN_SECRET" \
+  -d '{"label":"my-app"}'
+# → {"id":1, "apiKey":"ab12cd…"}
+
+# Revoke a key
+curl -XPOST http://localhost:8080/admin/keys/1/revoke \
+  -H "X-Admin-Secret: $ADMIN_SECRET"
+```
+
+To enforce API keys, uncomment `app.Use(middleware.APIKeyAuth(db))` in `main.go`.
